HUNIIDIFIER.

SPECIFICATIONforming part of Letters Patent No. 771,460, dated October 4, 1904.

Application tiled January 29, 1904. Serial No. 191,397. KNO model.)

To @ZZ whom, it may concern:

Be it known that I, ALFRED CLARxsoN, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Humidiiers,of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a perspective, and Fig. 2 a ver- IO tical central section, of my improved humidifier. Fig. 3 is a horizontal section of the cover-turret at line 3 3 of Fig. 2 looking' down, and Fig. 4 is a horizontal section at line 3 8 of Fig. 2 looking up. Fig. 5 is a I5 central' vertical section of the cover-turret at a line corresponding to line 5 5 of Fig. 4. Fig. 6 is a section of the water-nozzle. Fig. 7 is a sectional detail at line 5 5 of Fig. 4 of the' air-escape in the lower cleaning-ring.

My present invention is in the nature of an improvement on the atomizer set forth in my United States Letters Patent No. 675,556, granted June 4, 1901.

The main objects of my present invention are to provide means for automatically blowing out the water and air nozzles, either or both, but principally the water-nozzles, and for automatically cleansing the exterior of the humidifier from dust and iibrous waste.

Another object of my invention is to facilitate the construction of the main body of the humidifier.

In the drawings, 1 is the water-reservoir, which may be of any desired form, and 2 is the water-inlet to the basin.

3 is the strainer, which constitutes a lining for the bottom and sides of basin 1.

4 is an integral upwardly-extending ii'ange extending around the water-basin, and 5 is an upward extension of the side wall of the basin. 6 is a drip-channel formedbetween the iiange and said upward extension, and 7 the water-escape passage from the channel back into the basin. 8 is the basin-cover, which rests on said upward extension, with its outer surface sloping downwardly into the dripchannel and its lower edge slightly above the bottom of the channel, so that drip-water may fall of the cover into the channel and escape l back into the water-basin. Cover 8 is formed with an air-turret 9, having a plurality of airchambers which may be diminished or demy invention. These air-chambers will be readily provided by persons skilled in the art of making castings, the cover, with its turret, being preferably one casting.

The present form of chambered turret will be' best understood by reference to Figs. 3, 4, and 5. In Fig. 3, which is a horizontal sectional view of the turret looking down, cover 8 is formed within the turret-wall 1() with vertical partitions 11, which form, with wall 10, the four quadrant-shaped chambers 12 and the intersecting chambers 13, which separate the quadrant chambers one from another. The turret has two independent chambers 14 and 15 in its upper part, chamber 14 communicating with the four quadrant chambers and the chamber 15 communicating with the four intersecting chambers 13. Cover 8 in the present form is provided with six vertical water-nozzles 16, which are held in the cover and project outwardly thereof in line with correspondinghorizontal air-nozzles 17, which are each screw-socketed in the wall of the turret and lead into the described air-chambers therein.

I find in practice that it is of substantial importance to have the water and air nozzles removable, so that they may be readily replaced in case their exits become jammed. Accordingly I form water-nozzles 16 with exterior screw-threads 18, the exit-orifices 19 being constricted relatively to the watertubes 20, which extend from the bottom of the nozzles down into the water-reservoir. Preferably the tops of the tubes 20 are exteriorly threaded at and screw into holes through cover 8. The air nozzles have threaded Shanks 21 and constrictcd exits 22. If any of the nozzles become bruised, jammed, or clogged, they may be readily removed and new ones inserted. This is highly advantageous, as it does not necessitate the removal of the humidifier from its location on its supply-pipes. It is obvious that when air is forced through the air-nozzles across the wacreased, as desired, without departure from ter-nozzles that water will be sucked up and distributed as a spray into the room.

The foregoing part of my invention is an improvement on the construction of the socalled atomizer set forth in my said United States Letters Patent; but other features of my invention about to be described are of wide applicability, adapted to all forms of my humidifier and to various other forms of humidili'ers.

30 is a three-way cock-body having a side outlet 31 to the threeway cock-body 32. Cock-body 30 has its way 33 coupled with turret-chamber 15 by a coupling 34 and has its way coupled with turret-chamber 14 by a coupling' 37.

38 is a three-way plug' for cock-body 30, and 39 is the air-inlet nozzle to cock-body 30.

40 is the three-way plug for cock-body 32.

41 is a coupling connecting way 86 of cockbody 32 with the cleaning-ring 42, which is chambered at 43 and provided with a plurality of perforations 44 on its under side, so that air may be blown through the perforations down on the humidifier to blow off dirt, lint, and waste. Cock-body 32 has its way 45 connected by a coupling 4G with the chambered jet-cleaning ring 47, which is provided with air-escape ducts 48, discharging' against the exits of the air and water nozzles and directl y against the water-nozzle exits, blowing down into them. Consequently if the waternozzles become clogged a discharge of air under considerable pressure through the airescape ducts 48 will blow out lodgments in the water-nozzles, and such a discharge of air will also blow off lodgments on the outersurface of cover 8. Screens 50 are preferably employed to prevent foreign matter from being drawn into the air-chambers 12 and 13, the upper ends of these thimble-shaped screens being secured in the couplings 84 and 37.

As is well known, a goed deal of labor is required on humidiliers now in use to clean them without and within, and heretofore when water-nozzles or air-nozzles have become clogged it has frequently become necessary to remove the obstructions by inserting needles manually into the nozzles.

The air-turret is preferably formed with an orilice stoppered by a removable plug' 51. By taking olf cover 8 and removing plug 51 the turret may be readily cleansed, if necessary. Similarly the liet-cleaning ring is provided with a removable plug' 52. The orifices, respectively stoppered by plugs 51 and 52, are formed when the respective parts are cast and facilitate the casting of the turreted cover and jet-cleaning ring.

' As shown in Fig. 1, both three-way cockplug's 38 and 40 are open. In this position air under pressure will come in at 39 and be discharged not only through the air-nozzles 17, but also through the orifices 44 of the cleaning-ring' 42 and the jets 48 of the cleaning-ring' 47. When water is in reservoir 1, the flow of air through nozzles 17 will atomize the water sucked up through tubes 20 and nozzles 16. By properly turning plug' 40 air may be wholly shut off from both cleaningrings or admitted to one or the other ring, as desired. By properly turning plug 38 air may be shutoff from either turret-chamber 14 or 15, as desired. i

My invention may be embodied in many different forms. The shape of the cleaningrings is immaterial, and either one may be omitted without departure from my invention. The cock-bodies and connections shown are simply the preferred form of air-supply devices for the air-reservoir, of which the described turret is merely the preferred form,

,and for one or more cleaning-rings, which severally constitute a blowing mechanism.

I am the first, so far as is known to me, to provide any device for automatically cleaning either water or air nozzles; but in my present arrangement the water-nozzles are more etliciently cleaned by reason of the direct'action of the air-nozzles on the water-nozzles, the

air-passages and the water-passages of these nozzles being in line.

rIhe form in which the features of my, invention are embodied is wholly immaterial.

In my said patent the top of the water-reservoir is flat. I have found this to be objectionable, as water and dirt are apt to collect thereon. In my present construction the outer surface of cover 8 slants downwardly into drip-channel 6, so that water of condensation and dirt may be readily carried off the over surface of the cover into the drip-channel.

In accordance with my present invention thecover 8 rests on the upward extension or brim 5 of the water basin or reservoir 1; but the water-escape passages 7 form a vent for the water-reservoir, so that water may iiow readily into the water-reservoir. This is important, as generally in installing' the humidifiers a considerable number of them are attached to a common water main or pipe, and it is desirable to have the water stand at the same level in all the humidifiers, in order that the water-jets may discharge uniformly into the room. If the water in a number of the reservoirs or a common main stood at different levels, then the atomizing action of the water and air nozzles would vary in consequence of variation in distances through which the water would have to be lifted by the airjets.

The cock 38 has three ways a, and Z in its circumference, these ways being in one half of the circumference and separated by intermediate solid portions. The imperforate half is marked f. Cock 32 similarly has three ways m, a, and 0, all in one half of the circumference, the imperforate half being marked p and the ways m, n, and 0 being IOO IIO

separated by solid portions. In both these valves the imperforate half is adapted to cover two of the three ways in its cock-body. Detailed explanation of this matter is unnecessary, because it is readily understood by skilled mechanics.

The ring 42 constitutes an upper and the ring 47 a lower air-jet device. The shape of these rings as well as the shape of what I called the quadrant chambers, may be changed without departure from my in vention, for I use these designations for better description of the preferred form of my device and not as limitations of my invention. The air-turret or air-receptacle is made of cast metal to avoid all joints and consequent leakages and for economy of construction. The chambers 14 and I5 are the upper and the chambers 12 and 13 the lower chambers in the air-turret.

I wish to be understood as claiming my invention in the broadest manner legally permissible.
